Good sounding show, wish there were a better sourced copy than "liberated bootleg".

Good article describing the 25 most legendary concerts in the history of Las Vegas.
Here is what it says about the Dead:
5. Grateful Dead (with Santana), Las Vegas Ice Palace, March 29, 1969
At the height of their psychedelic prowess, the Dead rolled into town for their first Vegas visit (and last until 1981), playing a show that has long circulated in recorded form among the band's horde of tape-trading followers. "The playing is at its most exploratory and concentrated form, treading the familiar ground of these tunes with increasing assurance and darting off for angular, propulsive jamming," wrote fan Fred Heutte in 1997's DeadBase X: The Complete Guide to Grateful Dead Song Lists. But don't take his word for it, or ours—stream it for yourself, free, at

It's hissy and missing a few bits and pieces, but there are more than enough trippy Jerry Garcia solos, booming Phil Lesh bass bombs and bluesy Pigpen attitude to guarantee lovers of the early Dead's cosmic sound will bookmark and revisit the Ice Palace again and again.
19. Grateful Dead, Sam Boyd Silver Bowl, April 27, 1991
We didn't intend to tie up two of our 25 precious slots with one band, but, as former Sam Boyd facilities director Pat Christenson explains, the Dead's first Vegas stadium concert forever changed Southern Nevada's concert fortunes. "When we did the first Dead show, there really wasn't a philosophy of touring shows being able to bring tourists to town, but we sold out 32,000 a show for two nights," he says. "And after we did that first show we had a picture of a sold-out stadium, which we showed to Paul McCartney's people, and from there all the stadium shows started coming through Vegas: McCartney, U2, The Eagles, Metallica, Lollapalooza, George Strait ... The Dead opened everyone's eyes to Vegas' ability to do the biggest touring shows, which later moved over to the MGM, Mandalay Bay, the Joint [at the Hard Rock Hotel] and the other casino properties."
And, yes kids, there's a phish mention too, plus this tidbit from the lowlights section:
2.
Frank Zappa , Aladdin Theatre for the Performing Arts, September 10, 1977 Zappa’s road manager is found dead in his Aladdin hotel room the morning after the show, of apparent self-inflicted razor-blade wounds.
